- tend beyond section anel with the lower, the latter being in t e form of stub wings built directly into the hull structure. To these wing panels are hin ed for lateralextenson the sup orting sur aces of thercraft, the upper sur aces havin terminal panels which exille lower surfaces und are equipped with ailerons of the trailing edge type. The multiple power plant has its units not only formin a part of the engine section in this manner ut has them also braced to each other, while the panel as a whole is braced directly to the hull, and is arranged above the hydroplaning step of the4 latter in order to provlde a substantially vertical alinemen't between the center of lift and the center of gravity.
As regards' the rigid buildin of the mentioned wing panels into the hul it is known to me that some efforts `have been made previously to partially incorporate portions of the wing structure with that of ness*A with the step', "of efficiency.
the boat structure, but the construction to be hereinafter more fully explained progresses' far beyond'this point in so much as the wing beams-are not only built into the side of the boat hull but are reliably associated with compression braces forming intimate components of the hull construction. A most important addition in the built-in wing' structure will be discovered in the bracing for each Wingbeam whereby the latter are securely connected to each exfremity ofthe hydroplaning step of the beat, as Well as being oppositely guarded by' reaction braces, which complete a truss elfect forming an arrangement of the greatest strength to serve as a base'for the attachment of the aerial supporting surfaces. Advantages of an obvious nature reside in the result-ant security attained by the complete'inter-relation of these hull and wing structures.
Beginningthe more detailed descri tion by reference to the hullof the fiying oat, the numeral 10 indicates the keel upon which are erected floors 11 and over which is laid the outer planking 12 ofthe V-shapedr hydroplanng bottom, a false keel 13 being alln'ed exterlorly with'the keel 10 at the vertex of 'theangled bottom porti'nsa The planking 12 extended laterally in a manner` which is streamline in plan fromthe bow'b'f' the" boat Ato the hydro laning step.' 15 in order -t'o provide the auxi iary planing vfins", 16; `which in side elevation are also ,givencurves partaking of a` streamline nature. The V-shaped' bottom of the boat rises gradually from the step to the bow, while the tailportion 17 hasits flattened bottom'making'an angle of greater sharpfor well known reasons The upper surface oflthe hull is enlarged vforwardly -from av point aft the vertical plane of the step, the forward sweepy,lng roof line of the cabin 18 thus provided may be continued to merge into the nose of the hull in the roundcd manner denoted by the dotted line 18"',of Fig. 2. This root curve is, however,'destroyed or mutilated by the iintcrposition"4 of the short forward deck 19, the cabin front' being abruptly clit down to vertically meet this decl@ line. Horizontally, the deck19 is Icut away to provide the half-circular control cockpit 2Q at the front of the cabin und is edged by a combing 2()1| for the mounting of a removable cover-top 2l. This top is of semicylindrie-al formation to properly encompass the eock-pit and serves as a forward coiitinuation and termination of thc streamlines of the cabin 18. f
AS at present constructed, the cabin top 2l is built upon the'semi-circularly rounded cornice strip 22, which is also arcuate in cross section as is to be seen in Figs. 4: and 5. Spaced vertical :strips 23 connect a combingr band 24 to this cornice while the opposite sides of the cornice have fastened thereto the top strips 25 parallel to the diameter of its curvature and reinforced by a central strip 3G. The spaces in between the cornice and the combing band, as defined by the vertical strips 23, and those spaces defined by thc top Strips 25 are. covered with translnxrencies of some such suitable nature as celluloid or the like, except for the two foremost panels which are each adapted to be covered by a sliding door 26 which is movable. laterally andl arcuatcly, between upper and lower guides 27. By this arrangement the aviator within the cock-pit has at all times a practically unobscured vision while at the same time being protected from the weather and being able to manipulate the sliding Window 26 for the purpose of ventilation, when so desired. The method ot mounting this cabin top upon the combing 20 in order to provide for its ready removal, includes the placing of an exterior strip 28 adapted to overlie' the combing upon which rests the lower edge of the band 24, in the manner Well shown in Fig. 5. Plates 29 are carried interiorly and to firmly secure the top in extending outwardly fromthe portionofi' the hull ,inclosed by such flnsand'tlie superficial description ofthe hull construction may be concluded lby mention of. the entrance by vertical ribs' 23 to overlap the combing scuttle or hatchway 34 which let intorl'o Wliieh it intersects.

lowers tively, each the cabin roof 18 immediately aft ofy the control cock-pit to permit entrance into-tbe latter, and to admit light: into the interior of the hull. A hatch-cover 35, of a flexible, curtain nature, preferably, is employed for protection of the hull interior in inclement extremely secure manner which contemplates a built-in arrangement for on(` of the wings and a very sturdy method of bracing and interconnecting the remainder of the wing ling beams o7 and 58, respectively the leading and trailing beams of the lowermost wing panel, pass transversely and directly through the hull in the manner clearly illustrated in Figs. (i. 7, FS and 9, some distance below the cabin roof' 1.8 and slightly below the herr/.omai line oier the Forward decking l!) as rearwardly produced to this point. These beams are thusl firmly embedded directly into the hull and are `further secured by thil diagonal coniprcssion braces 37whirh converge from the respective beams to a secure anchorage upon the 'transverse hyd roplane step l5. Reaction braces 3f extend from each beam in the direetion omiosite from the step. lt is i'o be undersood.that a p'airot the comljiression braces and of the reaction braces is arranged for cachot the transversely projecting Wing beams, one brace ci each pair being located in each side oi the hull as a component portion thereof, being secured to rib frames 3l ln addition, upright standards 39 serve to vertically support the beam extremities, such uprights being arranged in the footings 39 and Vbeing incorporated intothe opposite sides of the hull. From this sturdy arrangement, it will'be apparent that .a truss bracing structure for the Wing bean'is has been achieved which is caing boat, and the'hnll thereof into aicorre- .lated Wh ol e;
'II-he upper-wing panel, through its lcading'` and trailing beams 40 and '40, is arranged for support and connection tothe tubwi'ng, and by tbeforward and rear Wing-,. p

The entire engine 4structure is then braced directly to the hull through the medium of 'the forward and diagonally extending post brace 49 which conncctsthe central point of the rear braces 47 with the eorrespoiuling point oi the lower wing beam B7. A second post brace 50, alinped in continuation of the main brace 49, extends in a similar forward oblique manner from tbe lower leading wing beam 37 for a secure anchorage in the boat hull in the footing port andarrangement ,ofthe power plant` units. The operation and control of such units is now to be considered. Each of the engines to be carried on .separate beds 45 in any desired manner that necessitates no particular illustration, is equipped with its separate means of adjustment for which purpose control wires 5l are trained over a pulley carried on the shaft extremity of the butterfly throttle valves vfor respective carbureters 52.-.,These'control Wires are earried 4laterallyinto the boat through 'protectivesleeves 53 alongthe forward lower wing beam 37 and are thence directed to separate control throttles denoted by the numeralsl an j mountedwithin thelore cabin of the y crafti-land 'to the supporting structure' for the across this portion of the cabin andi-mmediately below the conning'top.
pilotsi seat 55, which extends transversely 'Tn the matter of gasolene supply to the y i engines it' will be obvious vthat Where the gravity yfeed;system' is to be employed, as in the present instance, that it Wouldbe most necti-ng vfore and aft impractcable for a. .large reservoir to be arranged above the engines for this purpose since a tremendous head resistance would be offered thereby in addition to an undesirable raising of the center of gravity. Ac-
cordingly the system adopted for use in my- .over which is mounted the strainer 58. A
hand pump'fl adapted topropel liquid is placed near the pilot seat and serves as the junction for leads and 6l connecting to the sump 57 and the gravity tank 62 respectively, the latter being mounted in an elevated position by some such desirable means as the straps 63 to the center posts 48 of the engine section. This tank is formed with a sedin'ient trap or sink 64. along its bottom through which the lead 61 passes, as does the similar outlet lead (35 from the Windmill pump designated by the numeral 66 and also connected with the reservoir sump by means of a duct 67. The windmill pump includes the usual pump chamber in which is operable the piston 68 driven from the fan axis b9 through the medium of ordinary crank and connecting-rod means. The shaft 69 carries volute fan blades 70 which are adapted to be actuated by the Wind force created by the propellers when the machine is in flight.
Outlets for the gravity tank are present in the'exit valves 71 leading from the sink 64 by different ducts 72 to opposite carbureters 52 whereby each of the motors is given its independent supply of motive Huid. Should either of the pumps operate to fill the tapk to a higher level' than desired, a return pipe '73 having its upper open mouth position at the predetermined'level in the gravity tank, is .provided to conduct the excess liquid directly back to the reservoir 56. An oil tank 74 'is positioned on each of the engine beds provided by the beams 45 con- A winpost frames, for the ready service of the llbricating circuits',` While the radiators of separate water cooling systemsl arev mounted upon forward ...shelves provided by the bracket arms 76 irnmedlately in front of respective engine beds. An outlet 7 7 and inlets 78 extend between the radiators and the extremities of the cirfyuit provided for the cooling liquid within 'a`c' l1 engine .l j
To the stub-.wing panels erected on the up- -r'per and lower Wing beams are attachedlnain portion of this yoke )neled Winding reel ate the elevator vthe lower surfaces and are equipped with' trailing edge ailerons 81! At the extremities of the main panels `79 are erected the masts 79 to support anti-skid surfaces 80. From the upper extremities of these-masts which are thus at the hinging vledge of the main panels, there extend ther-supportingl 75 Wiresl 81a which are secured to the overhang ing edge ofthe wing tip panel for the suspension thereof, reaction wlres 81" bracing the masts back to theupper surfaces 79'with which they connect at points immediately above the wing posts 82 whichrjoin, in the usual manner the upper andlov'ver supporting surfaces. These posts, one of,l which 1s also arranged under each of the masts 7 9*, are cross-bracedlto each other by the usual tension Wiring 82, that portion of such Wiring denoted by the special numeral 82b being in v direct continuation of the supporting 'mem bers 81 and 81a-, so that the Wing tip panels are supported,via the masts,by suspension wiring tying such panels to the lower wing braces of the adjacent engine Wing post frames. Counterbalancing and completing the suspension system are the connecting wires 82 'which tie the panel 80 directly to the lower wing. Drift wires 83 extend rearwardly from the nose of the hull to respective yoke connections 83 with forward and rearward Wing posts 82, completing the draft system whereby the wing panels are most eiiicientlyrelated to the hull.
Rearwardly the empennage supported' upon the tail of the boat includes the eustomary vertical and horizontal fixed stabilizing surfaces 84 and 84'L to the latter of which are rearwardl hinged the elevator flaps85 While to the fbrmer is hingedly connected the rudder 86. Control of these adjustable surfaces is arranged Within the fore cabin of the boat hull and includes a subi stantially inverted U.yoke 87. which is in#A .termediately braced by a rib 88 and hasitsff extremities or arms commonly pivoted by the tube'shaft 89. In suitable brackets there I is mounted at opposite sides of the big'h'tf 87 a pair of hand Wheels f dualcontrol, since each' is equipped with a'. chan- 91, and the iexible cable commonly Wound upon the reels is' laid laterally across opposite wing panels and there connected to the respective trailingz ed ailerons 80. Fore and aftoscillation .of-'t U-shaped yoke upon its shaftV 89 will oper...

The rudder the cables 93 which-180v auatic are carried rearwardly from theoscillatable foot lever 94 mounted upon a 4small platwr to be immediately in The control form `indicated at 95 advance of' the pilots seat 55.
vcables. mentioned forthe operation of the alined with the direction of pull upon the cables. lach of these conduits, as shown in Fig. 14, has arranged therein a plurality of fii'red resilient wire guides 96, of a coil spring nature, through which the cables may easily pass with'minimum Wear.
It is now necessary to complete the dcscription of several of the constructional details to which reference has already been made. Reference will first be had to Fig. 10 in which is illustrated the folding back for the aviators seat, as arranged upon the roof brace 30.` This back includes a pair of bars 97 which are 'obliquely hinged in the inanner denoted by the numeral 98 to the oppo site sides of the hull, and carry upon their inner, ends the hinge fitting 99 which has ears 99aL spaced to embrace the central ear ory leaf 100 of thecoinplementary fitting, such central ears. being similarlv formed upon a single st'raprwhich is carried by the mentioned brace 36 and projects into a proper alinement with the ears of the hinge fittings 99,. Removable pins 101 are to be readily associated with the mating fitting portions when it is desired that the separate swing bars 97 form a back rest for the seat 55. At the time of entrance into the cockpit through the scuttle or hatch rest bars 97 may be readily loosed by ref moval of the pins 101` in order to permit the aviators to clamber over the seat into the fore portion of the cockpit where the con-- trols are located.
Directing attention now to Figs. 11, 12, and 13, a brief description of the socket fittings 43 and 47a will be undertaken. The former Socket includes a post terminal gripping p0rtion 102 which is mounted Upon a base plate 103, the latter of \vliich has apertured wire anchor-ing ears 104 projecting therefrom in two directions, while in a third direction the plate is elongated, slotted and lapped hack upon itself to provide the spaced cir-y cular hinge ears 105. With these ears there mates a similar ear 106 formed as the bight portion of the wing fitting 107, the extremities of which fitting are diverged from each other to form anchoring ears for the cross Wire bracing 89 extending between the wing posts. The wing fitting thus serves to receive the inner extremities oi the truss braces 8:2 which would otherwise be connected directly to the wing post frame of the engine section panel, necessitating the disconnection of the truss bracing at these hinging points when the Wings were dismounted from the .48 that the engine section defined by the Fig.
34, these back hull, a serious disadvantage which is evadedv by the novel 'construction of the presentinvcntion. Upon thc base plate 103 of the socket 13 there are provided thc raised bolt seats 108 which permit this plate to be firmly secured to its proper wir@ beam when connecting a wing' post frame 'terminal thereto.
The socket 47 is so designed as to permit of its being formed oi a single strip of' niaterial, the extremities 10i) oi which are each -75 folded back upon the main body portion and intermediately provided witl'nslotted `bight portions 110 `which serve as the anchorage forfthe cell wiring 44'. The extremities are thus produced and flanged to f'orm the opposite plates 111 of a socket adapted to` firmly scat an extremity ot',y thc transverse braces 4.-? of the origine section.
lt is by means ,of these transverse braces, in conjunction with the central wing beams upper and 4lower ving beams and their con necting framesare subdivided into inten mediate cells, each of which is to' be sepa rately braced by means of the truss wiring 44?, each' wire ruiming from one of the an choring ears on a socket 43 to the loop ears 110 of the diagonally oppositeI socket 47?, as is clearly apparent from an inspection ot.
Cellular intel-bracing of this character serves to tie the component parts of the engine section very firmly together.
While the foregoing description has been I concerned with the detail construction whereby my present invention is to be preferably carried out, it is believed that a further discussion of theh advantages afforded lby my invention soconstructed, will be in place. In employing a multiple unit power plant in an invention of'tliis character, it is most necessary that a draft system be organized Which shall tend to the equal subdivision of' work between the various motor with a degree of security far greater than i would be required with the motor Located in 'the hull.' It is a second requisite that the motors be securely braced to the wing structure to form a unified engine section, and it is a third requisite that the engine Section as i a whole and inclusive of the stubwving,y
panels and the vmotors be firmly connected" with the hull in accordance with a draft systeni forming a part of the engine section 'and continuing into the hull. .s Each oh-these requisites isso closely associa-ted withfits fellows as nearly to overla in scopeellut they may best be treated in istinct succession.
The first requisite is fulfilled theK eni-y v1s practically ployment of stub-wingpanels, oneof which built directly yinto the hull structure and is braced thereto, in addition, by use of the post brace50. In the' second p ace the motor units 'and separate wing panels are ,combined to form a unified engine section by the employment of the wing* post frames to serve as the sole supports for the separate engine beds and having the dual function of securely connecting the Yseparate panels. In addition the panels are to be connected by the center posts of the engine section which pass through the hull roof. An absolutely complete unification ,may then be attained by the transverse connection of separate motor units by braces 47 having anchorage upon the mentioned center posts, and by the employment of the cellular interconnection just described. Lastly the necessity to brace the engine section thus unified to the hull is desirably accomplished by use of the oblique post brace 49 extending forwardly from the juncture of rear transverse braces 47 with the center post, and outwardly to the lower leading wing beam 37, from which the hull brace 5() extends in continuation. Symmetry, proper distribution of the forces to be dealt with and the acquisition of a great strength by a comparatively simple draft and bracing sysvtem are thlus attained, owing solely to the method of connectingI the supporting surfaces to the hull, of connecting the motor units and Wing panels to form a unified engine section and the bracing of the engine section so unified directly to the hull.
While in the foregoing, however, there has thus been illustrated iny the drawings and describeddn the specification such combination and arrangement of elements as constitute one preferred embodiment of this invention, it is desired to emphasize the fact that such departures from the )articular embodiment disclosed may be ma e in later adaptations of this'invention as shall be recognized as vwithin the scope of the appended claims; i j
